I'm a laymen so don't take this as definitive but my understanding is Power = Volts * Amps. The amount of Amps going into something is the amount of electrons moving into it (water in a pipe). Volts is how hard you're pushing the electrons through a circuit (pressure in a pipe). Because of magic I don't understand amps is ~constant while how much force is behind those electrons have is changeable (how wide you open your faucet). Processor governors change the clock speed of the CPU (how many dishes you're washing). Dynamic voltage control is changing how hard you're pushing electrons through the CPU to let it stably operate at a given frequency (opening/closing the faucet as your scrubbing your dishes). By doing this we can lower the amount of Power (water) we use while getting the same amount of work done (dishes washed).
